It was only through the combined efforts of the White Hero and the secret protectors, who exploited a crack in Alronuth's soul-forged armor, that they could force the demon king to the corner.
Unfortunately, the demon king had not yet met his first death and had already entered his second phase. The reason for the early activation was that the demon king went berserk after witnessing his beloved demoness being slaughtered horribly right before his eyes, leaving nothing but a pool of blood and flesh.
Under the joint efforts of everyone who grouped and ganged up on the demon generals, they managed to defeat the three demon generals. The Demon King of Extreme Evil went berserk. He unleashed his full 9th Rank power, transforming himself into a monstrous form that eclipsed the throne hall. The ground trembled as he summoned infernal flames and torrents of darkness to consume everyone into his demonic domain realm.
